Stare at a painting on the wall. No matter how long you wait, it's not going to tell you what it's about. To find meaning in the spattering of paint, you must step back and gaze from many angles.

In his new book, "Varieties of Presence," Noe explores the many ways we use knowledge and skills to achieve a "presence" for the world in our thoughts and perceptions.
